LOCK.

SPECIFICATION forming part of Letters Patent No. 755,908, dated March'29, 1904.

' Application filed December 4, 1903. -Serial No. 183,816. (No model.) I

To all whom it may concern.-

' Be it known thatI, JAMES B. MILLER, a citiz en of the United States of America, residing at Kent, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Locks; andI hereby declare the following to be afull, clear, and exact descriptiori of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. p

This invention relates to improvements in locks, and especially to the class of locks termed keyless or combination locks.

An object of this invention is toprovide a lock of this character which will be strong, simple in construction, and comprise a small number of parts.

Another object of this invention is to provide' a spring-latch lock and dead-bolt all in one.

A further object of this invention is to provide independent combination mechanism for controlling the latch-lock and the dead-bolt, so that when both combinations are set in order to operate the lock it will be necessary to work two combinations from the outside or onecornbination from the inside.

With these objects in view my invention consists in providing two independent' tumblers, one of which is arranged to lock the outer spindle and the other is arranged to engage directly with the bolt, independent levers for operating the said tumblers, separate combinations for operating lthe said levers, and means for holding either or both of the tumblers in their inoperative positions.

My invention further consists in the features of construction and combination of parts, as illustrated in the drawings, described vin the specification, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View of the lock with the cover removed,

showing the arrangement of mechanism with both tumblers in their operative positions. Fig. 2 is a section on line 2 2, Fig. 1. Fig.

`3 is aview of the lock with the cover removed,

showing the arrangement of mechanism with both combinations worked so that the bolt can be operated from the outer side of the door. Fig. 4 is asimilar view showing the other spindle remains stationary.

lock'serving as a latch, both tumblers being held out of operation by means of st ops.V

In the accompanying drawings, 1 represents the casing, which holds the lock mechanism.

The spindles 3 and 4, which operate the bolt, are of the usual construction andare secured together by means of a neck portion 5, which is formed integral with the spindle 4 and enters a socket 6, formed in the spindle 3 and is'held in the socket by means of a screw 7, so that it is free to turn. This arrangement allows one lspindlerto be turned while the The respective spindles are provided with the usual knobs 3 and 9. On the spindle 3, which carries the inner door-knob, is arranged a hub which is provided with a square bore, so that it will turn with the said spindle 3. The hub 10 is provided with two arms11 and 12, preferably of the same length. On the spindle 4, which carries the outer door-knob, is mountp ed a hub 13, which is likewise provided with arms 14 and 15, and the arm 14 is formed longer than thefarm 11 on the hub 10.

The bolt 16 has a hollow shank portion 17,

' which is provided with arms 18 and 19, ar-

ranged to straddle the spindles. At the end of said arms 18 and 19 at each side thereof are formed lugs 20, 21, 22, and 23, respectively. One end of a coil-spring 24 is arranged in the hollow shank 17 .and the other end abuts against a lug 25 formed on the casing, so as to normally hold it in its outer position. When the knob 8 on the inside of the door is turned, the arm 11 on the hub 10 will engage with the lug 20, or the arm'12 will engage with the lug 22, according to the direction in which the knob is turned, and the bolt will be pulled back in the casing against the ac. tion of the spring 24. Also when the knob 9 on the outside of the door is turned the arml 14 on the hub 13 will come in contact with the lug 22, or the arm 15 will come in contact with the lug 23, thus drawing the bolt back in the casing against the action of the spring 24. Above the bolt is arranged -the tumbler,

' from ridge to ridge, constantly moving far-v a iiange 32, in which is formed a notch 33, arranged to receive the end of the arm 14, when the tumbler is in its lowest position, thereby preventing any movement of the said arm 14, and thereby preventing the outer doorknob from being turned. On the upper end of the tumbler 30 is formed a flange 34, and between the flange 34 and the side of the casing is arranged a coil-spring 35, so as to normally hold the tumbler in its lowest position.

Above the lock-spindle is journaled the combination-spindle 40, which is provided on the outside of the door with a knob 41. On the combination-spindle is mounted the combination-disk 42, so as to turn therewith. On the face of the disk 42 are arranged a series of cams or ridges 43. A lever 44 for lifting the tumbler 30 is pivoted at one end on a lug 45 in the upper part of the casing, and the other end is arranged to come into contact with the iiange 34 of the tumbler. A peg46 is secured on the lever 44 and extends in toward the face of the disk 42, so as to come into Contact with the ridges 43. The ridges are so arranged that when the combination-disk is turned back and forth through a whole or part of a revolution a number of times, according to a predetermined plan, the peg 46 will travel ther from the center of the disk, and the free end of the lever 44 is raised, which in turn lifts the tumbler 30 against the spring 35 and away from the arm 14, so that the bolt can be operated from the outer side of the door. Around the perimeter of the combination-disk are formed notches 47, and at the side of the combination-disk is arranged a spring 48, which is supported by lugs 49, formed integral with the casing. One end of the spring 48 is held in contact with the perimeter of the combination-disk, and when the combinationdisk is turned the end of the spring passing over the notches 47 indicates both to the sense of hearing and touch what portion of a revolution the combination-disk has been turned through.

In the side of the casing above the bolt is formed an opening 50, and within the casing a cam-faced block 51 is arranged to travel across the said opening. A lug 52 is formed on the block 51, and it extends into the opening 50, by means of which the block 51 can be moved up or down. A bar 53 is slidably supported in lugs 54 and 55, formed integral with the casing. A flat spring 56 is supported at one end between lugs 57 and 58, and at its other end it engages with the bar 53. This spring 56 serves both to hold the block 5l in position and to hold the end of the bar 53 against the cam-face of the block 51. The object of this arrangement is to hold the tumbler 30 out of engagement with the arm 14, so that the lock can be used simply as a latch, and to eect this result the combination is iirst worked lifting the tumbler 30, and before the bolt 16 is moved the lug 52 is shoved up in the opening 50, which carries up the block 51, and the block in turn moves in the bar 53 until the end thereof comes under the tumbler 30, locking it in its upper position.

On the arm 18 of the bolt 16 is formed a lug or projection 70. Below the bolt 16 is arranged a tumbler 71 in a guideway formed by lugs 72. On the tumbler 71 is arranged a iiange 73, and when the tumbler is in its operative position the flange 73 will come into contact with the lug 7 0 on the bolt 16 and prevent the bolt 16 being drawn back. A fiange 74 is formed on the lower end of the tumbler, and between this flange and the casing is arranged a spring 7 5. The mechanism for operating the tumbler 71 is similar to the mechanism for operating the first-mentioned tumbler 30, and comprises a combination-spindle 76, which extends through from side to side of the door, and is provided at each side of the door with a knob 77 and 78, respectively. On the combination-spindle 76 is mounted the combination-disk 80, which is provided with a series of cams or ridges 81. A lever 82 for pulling down the tumbler 71 is pivoted on a pin 83 andis provided with a peg 84, arranged to engage with the ridges on the face of the disk 80. The ridges are so arranged so that when the combination-disk is turned back and forth through a whole or part of a revolution a number of times, according to a predetermined plan, the peg 84 will travel from ridge to ridge, constantly moving farther from the center of the disk, and the free end of the lever 82 is depressed, which in turn pulls down the tumbler 71 against the action of the spring 75 and away from the lug 70 on the arm 18 of the bolt 16. Around the perimeter of the combination-disk 8O are formed notches 87, and at the side of the combination-disk is arranged a springp88, which is supported on lugs 89 formed integral with the casing. One end of the spring 88 is held in contact with the perimeter of the combination-disk 80.

In the side of the casing just below the bolt 16 is formed an opening 90. Within the casing a cani-faced block 91 is arranged to travel across the said opening 90, and a lug 92 is formed on said block 91 and extends into said opening 90. A bar 93 is slidably supported in lugs 94 and 95, formed integral with the casing. A iiat spring 96 is supported between lugs 97 and I,98, and its other end is arranged to engage with the bar 93, so as to hold one end of said bar against the said block 91. The object of the bar 93 is to hold the tumbler 71 out of engagement with the lug 70 on the arm 18. When it is desired to hold the tumbler 71 out of engagement with the said lug 70, the combination is first worked drawing down the tumbler, and the lug 92 is then moved down in the opening 90, which IOO carries down the block 91, which in turn moves in the bar 93'until the end thereof engages with a small lug 99, formed on the tumbler 71, which prevents the said tumbler from mov-- ing up and again engaging with the lug 71.
